The Keymount Muzzle Brake is compatible with 7.62x51mm and 5.56×45 threaded barrels and allows for quick attachment of Sandman-L™ or Sandman-S™ suppressors.
When not using a suppressor, the Keymount Muzzle Brake acts as a standalone device that reduces rifle recoil and minimizes concussion.
Constructed from stainless steel with a black finish, it fits 22 Caliber (.223-.224) firearms with 1/2-28 threads.
